Optical Design of Far Infrared Catadioptric System
折反式远红外光学系统设计

According to the superiority of an infrared search and track system in modern wars,a method for designing a catadioptric infrared optical system is proposed.In the catadioptric infrared optical system,both aberration and second spectrum are corrected by using the same infrared optical material.The design result meets the design requirements and is compatible with the uncooled focal plane array with a pixel size of 25μm.It can be used in an airborne infrared search and track system.
